NodeXl Library Like Microsoft.GLEE Not OPen in WPF Application

Please help me sir when i add the reference in a wpf application of the Libraries of NodeXl it will not successfully added in to the project reference the yellow icon is show on the DLL file ,

You are missing Microsoft.NodeXL.Core.dll. And if you are planning to use the NodeXLControl, then you also need Microsoft.NodeXL.Control.Wpf.dll.

The others in your list may or may not be needed, depending on what your application is doing. For example, Microsoft.NodeXL.ApplicationUtil.dll is needed only if you plan to use NodeXL's layout managers or zoom/scale control. Microsoft.NodeXL.Adapters.dll
is needed only if you are importing or exporting to various file formats. And Microsoft.NodeXL.Algorithms.dll is needed only if you are calculating graph metrics. This is all documented in the NodeXLApi.chm help file.

If you are using the NodeXLControl, then I recommend starting with the following list and adding to it as needed:

It usually means that Visual Studio can't find the referenced DLL. Click on Microsoft.NodeXL.Core.dll in Solution Explorer, look at the Path property in the Properties window, and check whether the DLL exists in the folder indicated by the Path property.

If that doesn't solve the problem, do the following experiment:

1. Start a new WPF project from scratch.

2. Insert this line into the Window1 constructor: Microsoft.NodeXL.Core.IGraph oGraph = new Microsoft.NodeXL.Core.Graph();

Also, make sure that the unzipped NodeXL DLLs are in a regular folder on your local machine, and not on a remote machine or in an otherwise restricted location.

Another thing to try: In Windows Explorer, right click Microsoft.NodeXL.Core.dll and select Properties. If there is an Unblock button in the properties dialog box, click the button. This has never been necessary on any of my machines, but
it's worth a try anyway.
